Girlfriend aura

Every man who's ever had a girlfriend knows about this, the strange halo of light, or maybe it's a stench which a male exudes when he's entered into monogamy with a female which seems to inexplicably make him more attractive to other females with whom he then cannot legally commiserate without violating the covenant of the girlfriend.

Perhaps this phenomenon is caused by a guy's knowledge that he no longer must seek a girlfriend. Most guys have it in their heads that they, for one reason or another, NEED a girlfriend at all times. Because of this, when he meets a prospective girlfriend, he acts how he assumes he must act in such an encounter. When he already has a girlfriend, he no longer must inhabit this state, and perhaps the lack of this state of mind is what is attractive...
